The 6.2-litre supercharged Hellcat V8 used by Dodge and Jeep, and the 2.0-litre turbocharged four-cylinder from the latest Honda Civic Type R can now be bought as crate engines from their respective manufacturers.

Hellcats for everyone

Fiat Chrysler will debut the new "Hellcrate" engine at the SEMA 2017, which kicks off shortly in Las Vegas.

As with the engine fitted the Dodge Challenger SRT Hellcat, Dodge Charger SRT Hellcat, and the Jeep Grand Cherokee Trackhawk, the off-the-shelf motor develops 527kW of power and 881Nm of torque.

The base Hellcrate kit is priced at US$19,530 ($25,409), and includes engine wiring harnesses, the accelerator pedal, ground jumper, oxygen sensors, a fuel pump controller and charge air temperature sensors.

The powertrain control module is unlocked, tuned to deliver 527kW, and optimised for use with the Tremec Magnum six-speed manual transmission.

An optional US$2195 ($2885) Front End Accessory Drive kit includes alternator, power steering pump, pulleys, and other gear to ease installation of the supercharged V8 engine.

Type R is for racing

While Fiat Chrysler will supply you a Hellcat engine without asking whether you intend to use it for a resto-mod, custom conversion or running a leaf blower, Honda's new Civic Type R create engine is only available "to US grassroots and professional racers for verified, closed-course racing applications through the HPD Honda Racing Line program".

Like the powerplant in the road-going Civic Type R, the crate engine develops 228kW of power at 6500rpm, and 400Nm of torque between 2500 and 4500rpm.

The K20C1 motor is available for US$6519.87 ($8482.35) before shipping and taxes.
